The 8 Most Flattering Under-$40 Swimsuits on Amazon

It’s that time of year again: The sun is peeking out, temperatures are rising, and I hate every swimsuit in my collection. Don’t get me wrong, I’m thrilled to welcome beach days to the horizon, but—like clockwork—I dread my annual swimwear shop. It always feels practically impossible to secure styles that are equal parts comfortable, supportive, and flattering. Luckily, I got a headstart this year and already struck gold on Amazon with the following under-$40 picks.  

Below, browse through the eight bathing suits with my stamp of approval. You’ll find actually supportive bikini sets, full-coverage one-pieces, and elevated on-trend styles that’ll serve as compliment magnets through summer. The best part? Prices start at $29. Just be sure to snag the swim styles that catch your eye ASAP—your vacation plans will be here before you know it.  

Editor-Loved Under-$40 Swimsuits

Saodimallsu Belted Tie-Strap One-Piece

I’ll be honest, I audibly gasped when I spotted this stylish Saodimallsu one-piece on limited-time sale. A major step up from your average bathing suit, the pick boasts a waist-cinching belt, full-coverage cut, and—my favorite detail—statement tie straps. Speaking of chic suits, this Qinsen option is Amazon’s number one best-selling monokini thanks to its sexy deep V-neckline and shaping double-lined material. Between us, I’m snagging both picks, considering they’ll serve as mainstays in my meticulously curated swim rotation.     

SweatyRocks Cupped Bikini Set

As someone with a fuller bust, I once avoided bikinis like the plague. Now, I’m shopping two-pieces with full confidence thanks to supportive, structured options like this SweatyRocks style. The swimsuit has underwire, fully lined cups, and adjustable straps you can tailor to your perfect fit. As for bottoms, it features a leg-elongating high cut and just the right amount of cheekiness. Another bikini worth scoring, this Cupshe number has high-rise bottoms and a criss-cross top with removable padding. Not to mention, it’s sold in a whopping 33 colorways to coordinate with the rest of your warm weather wardrobe.   

Hytensun Ruched Rosette Halter One-Piece

Don’t be surprised if you catch me sporting this Hytensun bathing suit on repeat all summer. I’m swooning over its on-trend rosette embellishments, which deliver an extra elevated look. It’s also structured with a halter-neck silhouette and flattering bodice ruching. I’m eyeing the white option to contrast with my summer bronze, but you can score the suit in two additional options. Before heading to checkout, you’ll also want to shop this timeless Bmjl one-piece that’s as practical as it is cute. 

Run to Amazon to score these flattering swimsuits while they’re available from $29.
